Manual Messaging Is Unreliable

For a launch announcement or critical reminder, manually hitting 'send' is stressful and prone to error.

Human Error & Distractions

Counting down to click 'send' is a recipe for mistakes. You get distracted, you're in a different timezone, you forget. The moment is missed.

Cron is Overkill

Setting up a server-side cron job just to send a one-off `curl` command is too complex for a simple, non-repeating notification.

Limited Native Scheduling

Slack's 'send later' is for simple delays, not a persistent, guaranteed engine for critical one-off announcements.

A Reliable Scheduler for Your Messages

WarpTrigger gives you a simple, powerful way to schedule one-time Slack notifications with precision and reliability.

Schedule by Timestamp

Tell us the exact future moment to send your message. We'll call the Slack webhook URL for you, guaranteed.

Example: Schedule a launch announcement for next Tuesday at 14:00:00 UTC.
Timezone-Aware Delivery

Need to send a reminder to a team in Tokyo at 9 AM their time? Schedule it from anywhere, and we'll deliver it at the right local moment.

Example: Schedule messages for any team, in any timezone.
Programmatic Scheduling

Our simple API lets you programmatically schedule notifications from your own applications, scripts, or CI/CD pipelines.

Example: POST /warps { url, payload, executeAt }

Schedule a Future Slack Message

Three simple steps to add precision timing to your Slack messages.

1. Get your Slack Webhook URL

From your Slack App settings, create an 'Incoming Webhook' for the channel you want to post to.

2. Craft Your Message Payload

Create the JSON payload for your message. Use Slack's Block Kit for rich formatting.
